The object of this invention is to provide a vacuum cleaner for domesticand other use which is hand operated, portable, readily usable, andeffective inz use. The invention relates to improvements in handoperated vaccuuin cleaning appliances of the type in which a pair ofbellows are arranged at each side of a central box containingy thedustreceiver,

the bellows being connected together by a suitable bar or rod so thatthey will work alternately, one pair of bellows drawing in air whilstthe other pair is expelling it and operated by a handle aiiixed to oneof the bellows and in which a second handle is aiiixed to the centralreceptacle andthe nozzle is carried at the end oda rigid tube attachedto the underside of this receptacle, so that the bellows can be operatedand at the same time the whole appliance can be moved over the surfaceto be cleaned by the person operating it, or it can dwell over anyparticular spot without ceasing its continuous suction operation. n

The present invention consists in a hand operated vacuum cleaning deviceof the type `referred to in which the handles are arranged to be movedlaterally, the movable handle is alifixed to the bellows by a curvedbracket, the air chamber and dust bag are open at the top and closedi bya lid which acts as a cap'for the dust bag, the air chamber taperstowards the bottom and the dust bag is carried on a loose pipe with aflared end to lit over the fixed air pipe.

The invention will be described with reference to the accompanyingdrawings. l

The vacuum cleaner is formed with a central receptacle A of rectangularshape in cross section, the sides a of which are inclined towards thebottom so that the area of the top of the receptacle is greater than thearea of the bottom. A pair of bellows B B1 is carried on each side ofthereceptacle A. Suction apertures b are formedin the walls a of thereceptacle A through which the air isdrawn when the bellows are beingexpandedand exhaust apertures 1 are formed in the outer walls b2 or' thebellows through which the air escapes when the bellows are beingcontracted. The outer walls b2 of each pair of bellows in May 29', 1924.ir Renewed are connected together by a bar vor rodl C pivoted at c 01 tothe walls so that as one pair of bellows is expanding the other pair iscontracting' and vice versa. l

An operating handle D is carried in a bail (Z oit vapproximately stirrupshape atlixed to the outer walls of one or other of the bellows and asecond handle E is carried in a bail e of approximately stirrup shape'aliixed tothe lreceptacle A.

The'bail d is bent inwards as shown to bring the handles D and E closertogether. The nozzle F is carried on the end oa short rigid tube f whichis connected by means of the bayonet joint f1 to a second rigid tube f2projecting through the bottom of the receptaole A. The orifice f3 of thenozzle F is so arranged that when in use the handles will be movedlaterally to and from each other.

The upper part of the receptacle A is closed lby a lid or cover AL whichcan be readily removed for the removal ofthe dust bag G from the insideof the receptacle A. The lid A1 also serves as a cap for the dust bag Gwhich is made of suitable material to allow air .to be. drawntherethrough but prevent .the passage of dust and dirt. It is attachedat the upper end to a rectangular rigid frame H and at the lower end isprovided with a ring or band h1 of rubber adapted to fit over a tube H1.The bottom end of the tube H1 is llared so that it can be readily placedover or removed Afrom the tube f2 towhich the nozzle carrying tube f1 isaliixed. The member H is supported on a ledge a2 arranged in thereceptacle A below the lidA1 and'is' held by the lid when the latter isin position.

In operation the person using the vacuum cleaner holds t-he two handlesD and E yand imparts a to and fro lateral movement to one Vor, -both sothat they are brought nearer together andthen further apart. Since onlythe handle D is affixed to the bellows, one pair of bellows iscontractedand then expanded and the other pair is expanded and thencon-v tracted so that a continuous suction is exerted by the nozzle onthe surface being cleaned. As the handles D and E are beingy operated,the person yusing the machine can move it together with the nozzle overthe surface to be cleaned, or can secure continuous suction ove anyparticular spot.
